The sample files are just a number of results. So I take all results from the Boinc user and put 100 with the highest mpts value into the samplefile. Afterwards the new sample file is sent to the user.

I've wondered about using this 50/50 split in the main samplefile myself. The problem is Muon1 will tend to select to highest muon percentage results in preference to the high Mpts one, so I don't know if a mixed samplefile would have the desired effect.

Just to clearify:I was thinking Yoyo@Home would help this project even more if 50% of the clients were using the samplefile created by Yoyo (highest Mpts) and the other 50% were using the original samplefile from this site.

That way, the lattices would be optimized in "two directions" at once.

Oh - I've just seen the effect of the BOINC client using totally different samplefiles - two totally different evolutionary pathways! If you scroll down on the page [TN]opyrt linked to, you get a plot coloured by user and you can see the (currently blue) BOINC results following a different line.

I would say the most interresting part of this optimisation right now is around 1100Mpts 1.25-1.43%. It would be really interresting to see what happened if Yoyo@Home only used samples from that area for a day or two.

I currently do not use any samplefiles from Stephen. For samplefile generation I use only the results delivered by the Boinc users. But all results are sent to Stephen and will be considered when samplefiles for the native client is generated.I'm thinking if I should also use Stephens samplefiles as input for my samplefile generation, to extract the highest Mpts results from both.But I will wait some more days to see how it evolves.
